A supercomputer is a computer with a high level of performance as compared to a general-purpose computer. The performance of a supercomputer is commonly measured in floating-point operations per second (FLOPS) instead of million instructions per second (MIPS). Since 2017, there are supercomputers which can perform over a hundred quadrillion FLOPS (petaFLOPS). Since November 2017, all of the world’s fastest 500 supercomputers run Linux-based operating systems.

Tianhe-2, a supercomputer developed by China’s National University of Defense Technology, retains its position as the world’s No. 1 system with a performance of 33.86 petaflop/s (quadrillions of calculations per second) on the Linpack benchmark. It was built by China’s National University of Defense Technology (NUDT) in collaboration with the Chinese IT firm Inspur.
